Spiritus Sancti is a first-person psychological horror game centered on ritual, faith, and the power of the spoken word. You play as Father Nathaniel, a young priest sent to investigate a suspected possession inside a small apartment on Vayra Street.
What begins as a routine investigation quickly turns into something far more sinister.

Your only defense is the sacred language of the ritual. Using your microphone, you must speak invocations aloud to repel the demon, weaken its influence, and survive the encounter. But the entity learns. It adapts. And faith alone may not be enough.
